Dear all, 

we use here the multi_array as a 2 dimensional matrix. Often we want to resize
the row or column dependent on some GUI event. Code could be:

void Bla::ResizeRows(size_t nRows)
{
   m_matrix.resize(boost::extents[nRows][m_matrix[0].size()]);
}

However this uses the 0-index of row count (i.e. 'm_matrix[0].size()') to
determine the size of the columns. Will this not crash if you have 0 rows? And
if so is there a better alternative?

wkr.
